To all whom t may concern Be it known that I, SAMUEL CoHN, a citizen of the United States, and a resident ofl New York city, in the county and State ofexact description, reference being had tothe accompanying drawings, forming partofV this specification, in which- Figure 1 is a sectional side elevation.

showingV one form of machine; Fig. 2 isa top plan view of the structure shown in Fig. l; Fig. 3 is a partial side elevation showing the parts of the machine in another position; and Fig. 4 is a cross-'section on the line XIII-XIII of Fig. 1. c

My invention relates to the class ofshirring or sewing machines for mantles; that is, machines for plaiting the mantles and passing the gathering or shirring string therethrough.

The object of the invention is to provide a simple, cheap and effective machine vof this character-which is not liable to 4get out of order.

An important feature of the invention consists in meansv for securing the compacting of the mantle into plaits before it is forced over the needles, or before the needles are forced through the plaits. i

In the ldrawings I show a form of machinel provided with fixed needle mechanism 'although the mechanism may be used in any machine'in which there is a relative movement between the plaiting means and needles.

' In the form illustrated a lever 2a is provided with the link 6a connected to the been'- tral slide.

The bottom of this slot is closed lby a bar or plate 29 secured to bar 27 by screws 30 and having transverse vertical slots. Through these slots in the floor of the central member extendy pairs of vertical pins or uprights 3l `having vertically extending slots 32 shown in Fig. 4. Through these'slots 32 extend rods 33' running longitudinally of the slide and 'acting :as guides. The vertically movable uprights or pin standards have their lower ends riding on a longitudinal Cam 34 secured to the frame of the machine underneath the slide. Each upright is provided at its lower end with a The slide in this case consists of a bar 27 having a longitudinal slot 28.:

side extension 35, which extension coperates with a cam 36 shown in Figs. 1, 3 and 4. These stationary'` cams 36 cause thestandards to move down over the beveled end portion of the cams 34. An upright plate 37 hasa flange or base portion screwed to the bar 27 near one end thereof, and an upwardly projecting pin 3S is set in the other end portion ofthe bar. The needle block 1 5a carries a forwardly projecting rod 39 Lsurrounded by a spring 40, which extends between the block and a pin 4l, the other end of the rod having a pin 42 acting against the block. grooved to allow the passage of the pin 38 and is fixed to the front end of rod 39. Secured tothe upright 18a is a pivoted hook 44 normally held down by spring 45, thi'sbe- 'ing arranged to interlatch with the pin 42 onV the rod 39. The needle blockis slidingly carried on rods 46 having surrounding spiral springs 47, and the depending pin 48 onthe needle block interlatches with a horizontally swinging hook 49 pivoted. to the upright'- 18a.` In the operation of this form of uprights 31,'which act as the central folding member. The movement of the handle 19@ through the medium of the shaft 5a,

gearing 41-3a, arm 2a and linka will then cause the slide to move toward the needle block. As this movement continues, the -uprights or pins 3l riding-on the cam 34 will be progressively moved down and out of the fabric by the cam 36 operating on the extensions 35. As theseuprights are successively moved down the fabrics is formed into plaits bythe lcooperation vo-f the uprights and the revolving-side members l1a which lare actuated 'by vpinions and side teeth or racks 8a; and these plaits will be laid plait by plait against the front plate- 43, each upright emerging from the fabric as the next upright approaches the contact point and'is ready to hold the plaited fabric pressed between itself and the grooved plate.' By the time the last upright is ready to move entirely out ofthe fabric, the plate 37 will bein a positionto hold the plaited fabric pressed between itself and the plate 43, as shown in Fig- 3. The continued movement of the slide will then push the rod 39 back toward the needle block, compressing the surrounding spring until the pin 42 interlatches with hook 44. This A front plate 43 is machine, a tubular mantlev is slipped on the ilalready moved down and out.

'moves the fabric farther back on the needle, and it will be noted that at the time the needles enter each plait the uprights have y In other Words, each plait as it is formed is fed onto the vneedles immediately after the uprights have emerged therefrom. The further f movement ofthe slide will cause the pin 38 on the bar or slide to bear against the needle block l5'a to carry it back on its rods until V the depending pin 48 interlatches with hook 49. AIhis moves the'needles back from the side members so as to expose the eyes for threading. The threading arm 2Oa and threading hook 23d are operated by the pin 212L located in the slot 22a.

- Onlthe return` movement of the handle,

Vthe spring 25a retracts said arm and the pin vmarked 50 on the'handle 19a engages hook 44, releasing the same from the pin 42 and allowingpthe spring 40 to come into action, thus pushingthe plate` 48 away `from the needle block. This operation results in carrying the thread back through the fabric and pushing the mantle partly or wholly off the needles. During this action, the hook 49 is llatohed 0n the lpin 48, thus holding the needle block in retracted position. The continued movement of the handle Will then release hoolr 49 by the direct engagement of some part of the handle with the lever `arm l part 51 of this hook. This will allow the operation repeated.

block` and needles to return to their -normal positions.` The mantle may then be removed, andV another mantley blank applied and the 'The advantages of my invention Vresult fromthe simplicity, ease and operation, and

the machines are not liable to get out-of order,the parts are comparatively few in number, and the operations are positive and effective.

Many changes may be made in the form and arrangement of the needle mechanism, the folders, the loperating mechanism7 etc.,

`without departing from my invention.
